How clean is clean enough?

Every year, the Glasswash team will clean 750,000 flasks, bottles and test tubes to be reused by Crick scientists. Their work is vital; one mistake and contamination could put life-changing scientific research at risk.


How do you clean?

To banish every last germ, the team doesn’t just wash the glassware, they bake it in an oven or pressure-cook it in an autoclave.

This attention to detail and scrupulous cleanliness is essential to the daily running of Britain’s biggest lab.

When handling glassware, it's all about the gloves. Disposable gloves protect the team's hands from contamination and keep clean glass pristine.


Meet Nicholas

Nick Sherwood is a Glasswash Technician, one of a team of twelve. Like all of his colleagues, Nick trained on the job and must maintain the team's high standards every minute of every day. Each technician is responsible for their own set of labs, arriving early to clear the dirty glassware and then clearing the decks again early afternoon. Each day they will run 20 loads through industrial dishwashers.

    Our roles are so different from the scientists. But when you see the work they're doing, you feel part of a whole.

  • Quote Tasnim

    Glasswash is such a lovely friendly team. When I was working in the labs upstairs I didn’t stop to think about where all the clean glassware came from, but now I realise Glasswash are the most important people in the building.
